general problems of the 2011 Buick Lucerne

The vehicle’s instrument cluster appears to be a non-original unit that may not be correct for the model year. The cluster is responsible for displaying the odometer and communicating with other vehicle systems. After purchase, I observed that diagnostic scan tools could not consistently access or communicate with multiple modules, and an experienced mechanic indicated the instrument cluster may be incompatible with the vehicle’s configuration. Because the odometer reading is displayed through this component, there is concern that the mileage may not be independently verifiable. The vehicle otherwise operates, but diagnostic communication inconsistencies raise questions about the reliability of system-level data. Additionally, there does not appear to be any service documentation indicating that the instrument cluster or odometer system was replaced, repaired, or recalibrated. This creates uncertainty regarding how the current mileage reading was established. The inability to fully verify mileage and system data may affect maintenance accuracy, resale valuation, and overall confidence in vehicle information.

Fuel pump relay is overheating to dangerously high temperatures. At least 211 f degrees. Causes the fuel pump fuse to melt leaving me stranded. Immediate replacement of the 20 amp fuse is necessary to get the car running again. The fuel pump relay gets really hot even if the ac is not on. Waited for hour and a half in near 100 f degree heat for a tow truck to it home. I’m lucky the car did not catch on fire. I know quite a few of the Buick Lucerne’s have had recalls regarding this item. Picture of the actual car is included. No police report was necessary as this was a breakdown situation. This has utterly disrupted my life because I do not have access to a car with good air conditioning until this problem is repaired.

Vehicle purchased used through carvana. Battery installed at purchase was approximately 10 years old and later failed, causing starting issues and an instance of power loss while driving that left the vehicle stranded. Battery has been replaced and original battery retained.

Several malfunction indicator lights in dash appeared suddenly. Car would not start after shutting off. Finally started and drove to repair shop. Diagnosed as faulty ride height sensor. Shop searched for part at several dealers and online and found the part was discontinued in 2021. I contacted Buick and was offered $1500 off on a new gm car. I have not received any suggestions on how to repair the car or remove malfunction indicator lights which I specifically asked for. The repair shop is waiting for me to find the part and I have not been able to find one. Dealers have no answer and neither does Buick. The repair shop says it will start if sensor is unplugged but suspension will not work and dash will still have malfunction indicator lights. It is my opinion to operate under these conditions, it would definitely be hazardous.

The contact owns a 2011 Buick Lucerne. The contact stated that after several attempts the vehicle failed to start-up without warning. Upon investigation, the contact linked the failure to the circuit board which was in the rear back seat. The contact stated that the rear seat latches had rubbed against the circuit box, causing the circuit to overheat. The circuit board was replaced. The contact then stated that upon entering his vehicle while in a parking lot, blueish colored smoke was coming from the vehicle. The contact removed the back seat and saw that the circuit board had started melting. The police were first called to the scene and the fire department then arrived and was able to extinguish the smoke before the circuit board caught on fire. Neither a police report nor a fire report was filed. The vehicle was towed to the dealer where it remained. The manufacturer was also notified of the failure and a case was filed. The vehicle had yet to be repaired. The failure mileage was 198,000.

Engine stopped running with no warning. It was repaired by the dealer at no cost under technical service bulletin (TSB) 15-na-051. In addition to the repairs specified in the TSB, the dealer had to replace the rear fuse box and repair the wire to the fuel pump because they were both damaged due to overheating. This is a fire hazard which should have been made a recall instead of an extended warranty.

On 9/1/18 I drove my car all morning late that night when I went to drive again it wouldn't start and I could smell a little burning. Checked the fuse box and it had blew out a couple of fuses so we changed them. 3days later it did the same thing we changed the fuses again and once again the blew now when we changed them it won't start at all. I had to keep changing the fuel pump fuse and a dealer said it was because of the metal of the seat touching the box .

The fuse box that is under the back seat keeps shorting out the relay for my fuel pump. Sometimes my car starts sometimes it doesn't.

Car was stationary, and attempted to start. Engine was not getting gas. Dealer identified rear fuse box/fuel pump relay was shorted out. He stated this could happen at any time- stationary or going highway speeds. Short in fuse box could result in fire. Short was probably caused by rear seat bracket rubbing on fuse box, as evidenced by markings on fuse box. There are many similar complaints on this same issue on internet sites. Why has this not been investigated?.

A manufacturer defect exists in the area of the rear fuse box located under the rear seat on the left side. The seat bracket applies pressure to the fuse box cover deflecting it from its standard position. This deflection puts lateral pressure on the fuel pump relay. This lateral force cause an weaked contact between the relay and the fuse box connectors. Increased electrical resistance causes the relay to overheat and melt its base and fuse box. The heat is intense enough to case the contact pins of the relay, and socket of the fuse box and softens the metal further degrading the continuity and increasing resistance. This mandates a replacement of the fuse box since simply replacing the relay after the heat damage may not be sufficient to remedy the defect. A manufacturer TSB exhists however, this component is more likely to fail on a longer high speed drive. If it fails at speed, vehicle control issues may arise among with driver panic when the engine stalls at highway speeds.

Upon further inspection, the contact noticed that there was excessive heat near the lower part of the driver's seat by the seat bracket and fuse box. The contact was concerned that there may be a potential electrical system defect or a defect concerning the fuel pump or fuel pump relay. The manufacturer was notified of the failure. The dealer was not contacted. The vehicle was not diagnosed or repaired. The approximate failure mileage was 82,000.

I was driving on a highway and stopped at a stop sign--when I accelerated to continue driving the car shifted into the gear for driving in the snow. The gear shift still was in drive. In the snow drive gear you get a bumpy ride and can only go 30 mph. I had on star at that time and they told me to turn the ignition off and it would get me out of that gear. I did that twice and it worked. I brought the car to a dealer in florida and they said it was caused by a faulty fuse--which they replaced. This same thing happened to me again this week; I now have 34,000 miles on the odometer. Turning the car off also worked. I will bring the car into Buick to have it checked. My concern is that the car will slip into the slow gear while I'm driving. Has anyone else reported this problem.
